I'll add one piece of advice - the number one key to success, at least in the whitetail business is: GOOD CLIENTS - when you find em - do whatever it takes it keep em! Always be honest - and prepare to run into the 80/20 rule - which is 80% of your clients, you will NOT make totally happy (even if you get em a filled tag) - 20% you will - you will get to repeats business out of the 20%. Don't be afraid to fire your bad clients - just don't invite them back. If one guy is having a bad time - try to get him away from your other clients - you'd be amazed at how one bad apple can bring down a camp of happy hunters.
Let your operation grow slowly - it does you no good to sign up 5000ac if you only book 8 guys per year...I've seen many awesome outfitters go under trying to get big too fast.
I've run several successful businesses in my life - I've needed the thickest skin in the outfitting business - most guys you book will expect you have 160" deer behind every tree and are pissed when they show up and don't see one after the second morning. Set the expectation up front - once they arrive - try to do whatever you can to make their stay a vacation!
Good luck!
